Description

Medium processing device

Technical Field

The present invention relates to a media processing apparatus such as an automatic teller machine, and more particularly to a media processing apparatus equipped with a separation and feed mechanism of a so-called overlap separation type for feeding banknotes one by one from a plurality of banknote bundles.

Background

In recent years, media processing apparatuses such as automatic teller machines have been required to process media such as banknotes (hereinafter, collectively referred to as banknotes) having various physical properties (material, printing, degree of distribution, wrinkles, and creases). The medium processing apparatus includes a separating and feeding mechanism for feeding banknotes one by one from a plurality of banknote bundles. The separation and feed mechanism is usually configured in an overlapping and separating manner in which rollers called a feed roller and a gate roller are arranged to overlap each other in a magazine shape. In addition, the overlapping amount of the two rollers is referred to as an overlapping amount.

In this overlap separation method, the paper money is slightly deformed between the feed roller and the gate roller when the paper money is separated and fed. Here, the feed roller is rotated by a motor or the like, and on the other hand, the gate roller is fixed in the feeding direction so as not to rotate. Therefore, the uppermost bill is fed in the rotational direction by the feed roller receiving the transport force, but the following bills are not fed due to the projection resistance of the gate roller. As a result, only 1 banknote can pass through, and 2 or more banknotes can be prevented from passing through.

In this system, the transport force by the feed roller and the resistance by the gate roller depend on the state of the minute deformation, and the amount of overlap determines the separation performance of the banknotes, so that the management thereof is very important.

Therefore, in the related art, for example, a careful design has been made to prevent the amount of overlap between the feed roller and the gate roller from undesirably changing due to the influence of expansion or contraction of the feed roller resin and the gate roller resin caused by the ambient temperature (see patent document 1).

Patent document 1: japanese laid-open patent publication No. 2015-507585

In the above-described overlap separation method, in addition to the above-described change in the ambient temperature, the adjustment of the overlap amount may be necessary as follows.

1) When handling various banknotes (media) having different physical properties, the adjustment is performed for each banknote (media)

2) Readjustment during maintenance when feed roller and gate roller are worn and overlap amount changes during operation

3) Adjustment at the time of assembly for suppressing variation in the amount of overlap due to part tolerance

However, in the above-described case, the adjustment ranges of the overlap amounts thereof are respectively largely different. Therefore, when the adjustment is performed by the same adjustment mechanism, the operation amount greatly varies depending on the adjustment amount, and therefore, there is a problem that it is difficult for the operator to determine or judge the adjustment amount. In particular, in operation, there is a case where an operator who does not have special knowledge about the apparatus performs an adjustment operation. In this case, if the operator performs an erroneous adjustment operation, the absolute value of the adjusted overlap amount is not known at the time of factory shipment, and there is a possibility that the absolute value needs to be measured again and readjusted.

Disclosure of Invention

The present invention has been made in view of the above points, and an object of the present invention is to provide a media processing apparatus capable of performing an adjustment operation without causing an operator to perform an erroneous operation even when an adjustment amount is largely different depending on an adjustment purpose when an overlap amount in an overlap/separation method is adjusted during operation of the media processing apparatus.

In order to solve the above problem, the present invention includes: a storage section that stores a plurality of media; a feed roller configured to feed the medium stored in the storage section to the outside of the storage section; a gate roller disposed opposite to the feed roller and configured to prevent the medium outside the feeding object from being carried out; and an operable adjusting unit for varying an amount of a gap between the feed roller and the gate roller; the adjustment means includes two types of first adjustment means and second adjustment means in the same mechanism.

Effects of the invention

According to the present invention, when adjusting the overlap amount in the overlap/separate method during operation of the medium processing apparatus, even when the adjustment amount is largely different depending on the purpose of adjustment, the operator can perform the adjustment operation without performing an erroneous operation.

Detailed Description

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Embodiment 1

Fig. 1 is a partial sectional view showing a configuration example of a medium processing apparatus 1 according to embodiment 1.

The medium processing apparatus 1 includes a hopper 10 for placing banknotes to be processed by an operator, a recognition unit 20 for recognizing the state of the banknotes with respect to the type, authenticity, transport state, and the like, a bag 30 for storing the banknotes, a take-out unit 40 for mainly storing the banknotes returned to the operator, a transport path 50 for connecting the banknotes to each other, and a separating and sending mechanism described later. The separating and feeding mechanism is mainly composed of a feed roller 111, a gate roller 121, and the like.

In the medium processing apparatus 1, the banknotes are set in the hopper section 10. The banknotes placed in the hopper section 10 are separated and fed out one by a separating and feeding mechanism in which the feed roller 111 and the gate roller 121 are arranged so as to overlap each other in a so-called cassette shape, and are transported into the medium processing apparatus 1.

The banknote to be transported is judged as to the processing content of the banknote by the recognition unit 20, and is distributed to the plurality of bags 30 based on the result and the number of passes. Meanwhile, the banknotes that are not assigned to the bags 30 are conveyed to the takeout section 40 that can be directly taken out by the operator.

Fig. 2 and 3 are diagrams illustrating the structure of the hopper section 10 for placing banknotes by the operator. Fig. 2 is a side partial sectional view showing a configuration example of the separation and feed mechanism 110 of the hopper section 10 shown in fig. 1, and fig. 3 is a front view showing the configuration example of the hopper section 10.

In the hopper section 10, a bottom plate 153 and a width regulating plate 152 constitute a storage space in which banknotes BN are placed. The placed banknote BN is stored in a position in contact with the pickup roller 171.

The hopper section 10 is provided with a separating and feeding mechanism 110 for separating and feeding the banknotes placed one by one. The separating and feeding mechanism 110 includes a feed roller 111, a gate roller 121, and a pickup roller 171 which are arranged so as to overlap each other in a magazine shape. Here, the amount of overlap of the feed roller 111 and the gate roller 121 is δ.

The banknotes placed as described above are rotated by the feed roller 111 and the pickup roller 171 in a state of being in contact with the pickup roller 171, and are conveyed in a direction indicated by an arrow of a broken line shown in the drawing. At this time, the door roller 121 stops without rotating. Therefore, since the banknotes receive the intrusion resistance from the gate roller 121 at the time of intrusion, a plurality of banknotes are not fed out at the same time, but the banknotes can be fed out one by one. The resistance to which the bill is subjected varies depending on the amount of overlap δ of the feed roller 111 and the gate roller 121. The optimum value of the overlap amount δ differs depending on the thickness and rigidity of the processed bill.

Fig. 4 is a diagram showing a configuration example of the knob portion 101 provided on the side portion of the hopper portion 10. The knob portion 101 is operated by the operator to adjust the overlap amount.

As will be described in detail later, the overlap amount δ of the feed roller 111 and the gate roller 121 can be changed by rotating the knob portion 101 in the arrow a direction shown in the figure.

Here, the knob portion 101 is provided with a position mark 101A, and the side cover 154 is provided with a scale 154A. This allows the operator to easily grasp the rotational position of the knob portion 101 (i.e., the overlap amount δ).

Fig. 5 is a side view showing a configuration example of the adjustment mechanism 100, fig. 6 is a front view showing a configuration example of the separation and feed-out mechanism 110, and fig. 7 is a side view showing an example of an overlap adjustment method of the separation and feed-out mechanism 110.

The hopper section 10 includes an adjustment mechanism 100 for adjusting the overlap amount δ of the feed roller 111 and the gate roller 121. The adjustment mechanism 100 is provided with a knob portion 101 to be operated by an operator.

In the separation and feed mechanism 110, the gate roller 121 and the gate roller shaft 122 are attached to the gate roller bracket 131. Further, the door roller bracket 131 is attached to the rotary shaft 132 by a bracket attachment screw 133.

The rotary shaft 132 is attached to the side wall 151 by a bearing or the like, not shown, and the door roller bracket 131 rotates in accordance with the rotation of the rotary shaft 132. By this rotation of the door roller bracket 131, the door roller 121 moves in the direction C1 shown in fig. 7. Thus, the overlap amount δ is changed by the movement of the gate roller 121.

On the rotary shaft 132, a butting member 161 is fixedly attached. The abutting member 161 is in contact with the fine adjustment screw 102 in a state of being pushed by a spring not shown. The abutting member 161 is rotated about the rotation axis 132 by the translational movement of the fine adjustment screw 102 and the coarse adjustment screw 103.

Fig. 8 is a sectional view showing a detailed structural example of the adjustment mechanism 100. In the adjustment mechanism 100, a knob portion 101 for an operator to operate protrudes at its front end portion from the side cover 154 so as to be accessible to the operator.

The adjustment mechanism 100 includes a fine adjustment screw 102 (pitch of its thread is P1) as a 1 st overlap adjustment means that rotates and translates in the arrow direction B of fig. 5. Further, the adjustment mechanism 100 includes a rough adjustment screw 103 (pitch of its screw is P2) as a 2 nd overlap adjustment means. Here, the pitch of each thread is in the relationship of P2> P1.

The adjustment mechanism 100 is provided with a contact member 161 that can rotate about the rotation shaft 132 by coming into contact with the fine adjustment screw 102. In the present embodiment, the fine adjustment screw 102 is attached to the inside of the rough adjustment screw 103, and the male screw portion 102M of the fine adjustment screw 102 is coupled to the female screw portion 103N of the rough adjustment screw 103.

The rough adjustment screw 103 is attached to the support member 141, and the male screw portion 103M of the rough adjustment screw 103 is coupled to the female screw portion 141N of the support member 141. Further, the rough screw 103 is fixed to the knob portion 101 by a fixing screw 101B. Therefore, if the knob portion 101 is turned, the rough screw 103 is rotated.

The fine adjustment screw 102 can be fixed to the coarse adjustment screw 103 by a fixing screw 103B. Here, when the overlap amount is adjusted by using the rough adjustment screw 103, the fixing screw 103B is tightened, and the rough adjustment screw 103 and the fine adjustment screw 102 are fixed. By doing so, when the rough adjustment screw 103 is rotated, the fine adjustment screw 102 is also rotated at the same time. When the overlap amount is adjusted by using the fine adjustment screw 102, the coarse adjustment screw 103 is not rotated by loosening the fixing screw 103B, and the fine adjustment screw 102 can be rotated alone.

Fig. 9 is a cross-sectional view showing an example of the state of adjusting the overlap amount by the fine adjustment screw 102 as the first adjusting means. The fine adjustment screw 102 is used for adjustment requiring relatively fine analysis capability, for example, to suppress variation in the overlap amount due to part tolerance during production.

Here, by providing the step s between the knob portion 101 and the fine adjustment screw 102 which are directly operated by the operator, the operator does not erroneously touch the fine adjustment screw 102. Therefore, when the fine adjustment screw 102 is operated, the tool 181 and the like are used.

The fine adjustment screw 102 is rotated in the direction of an arrow D1 in the figure (here, the rotation angle is θ 1). At this time, the fixing screw 103B is in a relaxed state so as not to contact the fine adjustment screw 102, and the coarse adjustment screw 103 does not rotate at the same time. Here, it is preferable that the rotation of the coarse adjustment screw 103 be restricted by a fixing means not shown.

The vernier screw 102 is translated in the direction of arrow D2 by an amount proportional to the pitch P1 thereof, and the rotation shaft 132 is rotated by pressing the abutting member 161. Thereby, the amount of overlap varies according to the structure shown in fig. 7. Let the amount of change in overlap here be δ 1.

Here, if the adjustment sensitivity (δ 1/θ 1) is defined as the ratio of the rotation angle θ 1, which is the amount of operation by the operator, to the overlap variation δ 1, the adjustment sensitivity in the present operation is determined by the component tolerance amount such as the outer diameter of the feed roller 111 and the gate roller 121.

Fig. 10 is a partial cross-sectional view showing a method of adjusting the overlap amount of the coarse adjustment screw 103 as the second adjusting means.

The rough adjustment screw 103 is used when the adjustment value thereof changes in a relatively large range, such as when the operator handles various banknotes having widely different physical properties, and arbitrarily adjusts the overlap amount according to the banknotes. Here, the rough adjustment screw 103 can be operated by the operator directly touching it with a hand, but a special tool or the like may be used for the operation.

When the operator rotates the knob portion 101 in the direction of the arrow D3 in the figure (here, the rotation angle is θ 2), the lead screw 103 attached to the knob portion 101 rotates. At this time, the set screw 103B is fixed and the fine adjustment screw 102 is also rotated. As the rough adjustment screw 103 rotates, the rough adjustment screw 103 and the fine adjustment screw 102 are translated in the direction of arrow D4 in an amount proportional to the pitch P2 of the rough adjustment screw 103, and the rotation shaft 132 is rotated by pressing the abutting member 161. Thereby, the amount of overlap varies in the structure shown in fig. 7. Let the amount of change in overlap here be δ 2.

Here, if the adjustment sensitivity (δ 2/θ 2) is set as the ratio of the rotation angle θ 2, which is the operation amount of the operator, to the overlap variation δ 2, the adjustment sensitivity in the present operation is set in accordance with the range of physical properties such as rigidity of the bill to be used.

Here, the 2 nd overlap adjusting means is provided with position indicating means for discriminating the position of the adjusting means as shown in fig. 4. Therefore, the rotation angle θ 2 as the operation amount of the operator is set here so as to be the overlap amount at the position indicated by the position indicating unit that ensures the separation performance of the processed banknotes.

As described above, in the medium processing apparatus 1 of the present embodiment, in order to adjust the overlap amount in the separation and feed mechanism, two types of adjustment means, i.e., the first adjustment means and the second adjustment means, having different adjustment sensitivities are set according to the adjustment purpose. Further, by changing the overlap of the adjustment sensitivities of the respective adjustment units in accordance with the adjustment purpose, it is possible to prevent the operator from performing an erroneous adjustment when performing the adjustment work. The adjustment sensitivity is represented by a value obtained by dividing the amount of change in the gap (the amount of change in the overlap) by the adjustment means by the operation amount of the adjustment means.

In the present embodiment, as described above, the fine adjustment screw 102 (pitch P1) as the first adjustment means and the coarse adjustment screw 103 (pitch P2) as the second adjustment means have a relationship of the pitch P2> P1. Thus, for the adjustment matching the physical properties of the bill, which is the object of the second adjustment, the adjustment range of the overlap amount is wide, so that the change in the overlap amount can be set relatively large (sensitivity is increased) with respect to the operation amount.

In contrast, for adjustment for suppressing variation in the overlap amount due to part tolerance at the time of production, which is the object of the first adjustment, since the adjustment range of the overlap amount is narrow, it is possible to set the variation in the overlap amount to be relatively small (to make the sensitivity low) with respect to the operation amount.

Here, the purpose of the first adjustment and the second adjustment may be changed arbitrarily as long as the adjustment sensitivity is set in accordance therewith. In the present embodiment, the adjustment sensitivity of the first overlap adjusting means is set to be lower than the adjustment sensitivity of the second overlap adjusting means, but may be set to be the opposite depending on the purpose of adjustment.

In the present embodiment, the position indicating means capable of determining the adjustment position of the coarse adjustment screw 103 as the second overlap adjusting means is provided, but the position indicating means may be provided in the first overlap adjusting means for the purpose of investigation. In this way, by providing the position indicating means which can be visually recognized by the operator in at least one of the adjusting means, the absolute value of the overlap amount can be determined. Further, in the present embodiment, the position of the first adjusting means is also moved during the overlap adjustment by the second adjusting means.

Fig. 11 is a diagram for explaining a problem concerning a structure in which the first adjustment unit 902 and the second adjustment unit 903 can move independently. As shown in the figure, in the case of a configuration in which the first adjustment means 902 and the second adjustment means 903 are independently movable, for example, in the case where the first adjustment means 902 is moved by a distance x1, since a gap is generated between the abutting member 961 and the second adjustment means 903, the second adjustment means 903 needs to be moved by a distance x2 in order to visually fill the gap, and it is conceivable that the operation becomes complicated and causes erroneous adjustment.

However, in the present embodiment, the first adjustment means can be moved by the second adjustment means, and the above-described problem can be avoided. Further, in the present embodiment, the fine adjustment screw 102 as the first adjustment means is coaxially attached inside the coarse adjustment screw 103 as the second adjustment means. In this configuration, the outer diameter is determined only by the size of the rough adjustment screw 103, and therefore a relatively simple mechanism can be realized.

(2) Embodiment 2

Since the media processing device according to embodiment 2 has substantially the same configuration as the media processing device 1 according to embodiment 1 and performs the same operation, the same reference numerals are used for the same configuration and the like in the two embodiments in the following description, and the description thereof will be omitted, and the difference between the two will be mainly described below.

In embodiment 1, the fine adjustment screw 102 as the first adjustment means is provided inside the coarse adjustment screw 103 as the second adjustment means, but the two means may be provided in different locations as in the present embodiment.

Fig. 12 is a side view showing a configuration example of the adjustment mechanism according to embodiment 2, and fig. 13 is a rear view showing a configuration example of the separation and feed mechanism according to embodiment 3.

The hopper section 10A includes an adjustment mechanism 200 for adjusting the overlap amount δ of the feed roller 111 and the gate roller 121. The adjustment mechanism 200 includes a knob portion 101 to be operated by an operator. Here, the knob portion 101 is provided with an adjustment position indicating means that can be visually recognized by an operator as shown in fig. 4, as in embodiment 1.

In the separating and feeding mechanism 210, the gate roller 121 is attached to the gate roller holder 231 via a shaft not shown. The door roller bracket 231 is rotatably attached to the rotary shaft 232 by a bearing or the like, not shown. The rotary shaft 232 is rotatably attached to the side wall 151 by a bearing or the like, not shown. The abutting member 161 is fixedly attached to the rotary shaft 232.

Fig. 14 is a diagram showing an example of a method of adjusting the overlap amount of the fine adjustment screw 202 as the first overlap amount adjustment means according to embodiment 2. The adjustment of the overlap amount by the fine adjustment screw 202 is performed, for example, while suppressing a deviation of the overlap amount due to a part tolerance at the time of production.

In the present embodiment, the fine adjustment screw 202 (the pitch of the screw threads is P1) is attached to the screw support portion 204. The screw support portion 204 is fixedly attached to the rotary shaft 232 and is rotatable by rotation of the rotary shaft 232.

Further, the vernier screw 202 and the gate roller bracket 231 come into contact with each other while being pressed by a spring contact surface 231P, not shown. Here, since the door roller bracket 231 is rotatably attached to the rotary shaft 232 as described above, if the vernier screw 202 is rotated in the direction D5 in the figure (here, the rotation angle is θ 1), the door roller 121 moves in the direction C2. By the movement of the gate roller 121, the overlap amount is changed (here, the change amount of the overlap is δ 1).

Fig. 15 is a diagram showing an adjustment method of the coarse adjustment screw 203 as second overlap adjustment means according to the present embodiment. The adjustment of the overlap amount by the rough adjustment screw 203 is used when the operator operates the apparatus according to the present embodiment, for example, when handling banknotes having greatly different physical properties such as rigidity, the overlap amount is arbitrarily adjusted. When the operator rotates the knob portion 101 in the direction of the arrow D6 (here, the rotation angle is θ 2), the coarse adjustment screw 203 attached to the knob portion 101 rotates.

The abutting member 161 is in contact with the rough adjustment screw 203 by a spring not shown. Then, the contact member 161 is pushed out by the translational movement of the rough adjustment screw 203, and the rotation shaft 232 rotates.

The door roller 121 is moved in the direction C3 by the rotation of the rotary shaft 232. By the movement of the gate roller 121, the amount of overlap varies. Let the amount of change in overlap here be δ 2.

At this time, as described above, the fine adjustment screw 202 as the first overlap adjustment means is attached to the screw support portion 204 fixed to the rotation shaft 232. Therefore, at the time of the overlap adjustment by the second overlap adjustment unit, the fine adjustment screw 202 as the first overlap adjustment unit also moves at the same time.

Here, if the adjustment sensitivity (δ 2/θ 2) is set as the ratio of the rotation angle θ 2, which is the operation amount of the operator, to the overlap variation amount δ 2, the adjustment sensitivity in the present operation is set so as to match the physical properties such as the rigidity of the bill to be used and the scale position of the adjustment position indicating means.

According to the present embodiment as described above, the same effects as those of embodiment 1 can be exhibited, fine adjustment can be performed more accurately by the screw structure, and downsizing can be achieved by the built-in structure.

(3) Embodiment 3

Since the media processing device according to embodiment 3 has substantially the same configuration as the media processing device 1 according to embodiment 1 and the media processing device according to embodiment 2 and performs the same operation, the same reference numerals are used for the same configuration and the like in the two embodiments in the following description, and the description thereof will be omitted, and the difference between the two will be mainly described below.

In the above-described embodiment 1 and embodiment 2, the screw is used as the first and second overlap adjusting means, but another means may be used as in embodiment 3.

Fig. 16 is a partial side view showing a configuration example of an adjustment mechanism 300 according to embodiment 3. The hopper section 10B includes an adjustment mechanism 300 for adjusting the overlap amount δ of the feed roller 111 and the gate roller 121.

The adjustment mechanism 300 includes a knob portion 101 to be operated by an operator. Here, the knob portion 101 is provided with an adjustment position indicating means which can be visually recognized by an operator as shown in fig. 4, as in embodiment 1.

Fig. 17 is a diagram showing an example of the appearance of the fine adjustment plate 302 used as the first adjustment means in embodiment 3.

The fine adjustment plate 302 includes a bearing portion 302H for passing a shaft therethrough, a circular fitting portion 302F for attaching the fine adjustment plate, and a long hole portion 302L for fixing the fine adjustment plate with a screw or the like at a predetermined phase. Here, if the center of the bearing portion 302H is HO and the center of the fitting portion 302F is FO, the center is eccentric by the distance a.

In the present configuration, the position of the shaft attached to the bearing portion 302H can be finely adjusted by adjusting the attachment angle of the fine adjustment plate 302, which will be described in detail later.

Fig. 18 is a side view showing a configuration example of the separation and feed mechanism 310 according to embodiment 3. In the separation and feed mechanism 310 of embodiment 3, a fine adjustment plate 302 is attached to a gate roller holder 331. Here, the door roller holder 331 is formed with a circular hole, and the fitting portion 302F of the fine adjustment plate 302 is fitted into the hole without a gap.

Further, a door roller shaft 322 is attached to the bearing portion 302H of the fine adjustment plate 302. Then, the fine adjustment plate 302 is fixed at a predetermined angle by a plate fixing screw 302B.

Fig. 19 is a diagram showing an example of a method of adjusting the overlap amount of the fine adjustment plate 302 as the first overlap adjustment means according to embodiment 3. The adjustment of the overlap amount by the fine adjustment plate 302 is performed, for example, while suppressing a deviation of the overlap amount due to a part tolerance at the time of production.

In a state where the plate fixing screw 302B is loosened, the fine adjustment plate 302 is rotated in the direction D7. The fine adjustment plate 302 rotates about the center FO of the fitting portion 302F. Let θ 1 be the amount of rotation at this time. At this time, the door roller shaft 322 attached to the bearing portion 302H of the fine adjustment plate 302 also moves. Let δ 1 be the change in the overlap amount with respect to the present movement, and a (1-cos θ 1) be the movement amount at that time. After adjustment, plate fixing screw 302B is tightened to fix fine adjustment plate 302.

Fig. 20 is a diagram showing a method of adjusting the overlap amount between the rough adjustment screw 203 and the abutting member 361 as the second overlap adjustment means in embodiment 3.

The adjustment of the overlap amount by the rough adjustment screw 203 is used, for example, when an operator operates the medium processing apparatus according to the present embodiment or when handling banknotes having greatly different physical properties such as rigidity.

This adjustment is the same as that of embodiment 2, but in this embodiment, the fine adjustment plate 302 as the first overlap adjustment unit is also moved by the second overlap adjustment unit.

Fig. 21 is a partial side view showing a modification of the medium processing apparatus according to embodiment 3. The fine adjustment plate 302 may be attached so as to move the rotation shaft 332 in the Y1 direction in the figure instead of the door roller 322. In this case, the fine adjustment plate 302 has a circular hole opened in the side wall 351, and the fitting portion 302F of the fine adjustment plate 302 is fitted in the hole without a gap.

In a modification of the media processing apparatus according to embodiment 3, the fine adjustment plate 302 as the first overlap adjustment unit moves the abutting member 361 as a part of the second overlap adjustment unit.

As described above, in embodiment 3, by using a thin member such as the fine adjustment plate 302 as the first adjustment means, a compact mechanism is realized and the manufacturing cost can be reduced.

(4) Embodiment 4

Since the media processing device according to embodiment 4 has substantially the same configuration as the media processing devices according to embodiments 1 to 3 and performs the same operation, the same reference numerals are used for the same configuration and the like in the two embodiments in the following description, and the description thereof will be omitted, and the difference between the two will be mainly described below.

In embodiments 1 to 3, the first adjusting means and the second adjusting means are means for directly changing the overlap amount, but one adjusting means may be means for indirectly changing the adjustment sensitivity of the other adjusting means as in embodiment 4.

Fig. 22 is a side view showing a configuration example of the overlap adjustment mechanism 400 according to embodiment 4.

The overlap adjustment mechanism 400 according to embodiment 4 includes a first adjustment screw 402 as a first adjustment means and a second adjustment screw 403 as a second adjustment means. The first adjustment screw 402 is attached to the first support member 442, and the second adjustment screw 403 is attached to the second support member 441.

Here, the first support member 442 is fixedly attached to the side wall 451, whereas the second support member 441 is attached to the side wall 451 by a slide mechanism, not shown, and is movable up and down with respect to the side wall 451. The second support member 441 is urged by a spring or the like, not shown, so as to be in contact with the first adjustment screw 402.

In the present structure, the overlap adjustment is performed using the second adjustment screw 403. The operation is the same as in embodiments 1 to 3, and therefore, the description thereof is omitted here.

If the first adjusting screw 402 as the first adjusting means is rotated in the direction D7, the second adjusting screw 403 and the second supporting member 441 surrounding it are moved in the direction Y1 in accordance with the translational movement of the first adjusting screw 402.

Since the angle (θ ') of rotation of the abutting member 461 when the second adjustment screw 403 is rotationally translated (the amount of translation here is X1) is changed according to the position of the second adjustment screw 403 in the Y1 direction, the adjustment sensitivity (θ'/X1) is changed.

According to the present embodiment, although the configuration is slightly different from that of the above-described embodiments 1 to 3, the adjustment sensitivity of one adjustment means is indirectly changed by the other adjustment means, and substantially the same effect as that of the above-described embodiments can be obtained.

(5) Other embodiments

The above embodiments are illustrative of the present invention, and the present invention is not limited to these embodiments. The present invention can be implemented in various forms without departing from the spirit thereof. For example, in the above-described embodiment, the processing of various programs has been described sequentially, but the present invention is not limited to this. Therefore, the order of processing may be replaced or the processing may be performed in parallel as long as no contradiction occurs in the processing results. Further, the program including the processing blocks of the above embodiments may be stored in a non-transitory computer-readable storage medium, for example.
